i nTTERNAL-COMBUSTION E1`l'G-I1TE.v

` Application mea october 2e, 192e. serial No. 144,294.

The present invention relates 'to an inter-v nal combustion engine preferably of the four cycle type and lits object is to provide a valve mechanism for engines of this type 5 which shall effectively control the ignition and exhaust, which shall operate noiselessly,

and which shall conduce to the obtaimng of maximum elhciency. n

Another important object of the invention lies in the provision of a valve mechanism which is simple in its construction, re-

liable in its operation, inexepensive to manufacture, and' otherwise well adapted to the purpose for which it is designed.- l5

jects in view., as will appear as the description proceeds, the invention resides 1n certain novel features of construction, and in the combination and arrangement of parts as 2o will be hereinafter more fully described and containing a plurality of cylinders 6. The

cylinder block may be of any conventional formation but is herein shown as having an integral yhead in which are mounted the'usual spark plugs 7. The cylinder block has a water jacket 8 associated therewith and has also .the head. It islto be noted that on the v4.0 side of the cylinder block there are provided aplurality of slide ways 9 which are disosed vertically,vthere being .two slide-ways ihr each-c linder. o Each cylinder is also provided wit two'portslO which lead into the upper portions of the slide-ways. The pistons-in the cylinder 6 are denoted by the numerals 11 and have the usual connecting rods `12associated therewith and associated witha crank shaft 14 on which is fixed a 50. gear 15 meshing with another gear 16 which operates a second or auxiliary crank shaft y17 one-fourth crank shaftleed. v

ing rods 18 yare engaged wi the cranks of the auxiliary crank shaft 17 and extend through the openings 19 in the crank shaft upwardly alongside of the engine blocks.

With the above and numerous other ob.

' merel Connectthat numerous changes inthe details 4of* con- ASlide valves Vvare slidably mounted in the slide-ways 9. Each valve V includes a flat bar-like body 2O which is provided at its lower end with a'pair of elongated loops 21 in extensions thereof. The connectin rods 18 are provided with laterally exten ing pins 22 which extend into the loops 21 so as to providev a lost-motion connection between the connecting rods and the valves. The intake manifold is denoted by the numeral 23 and the exhaust manifold b the numeral 211. The valve mechanism will be timed to fire the cylinders in any preferred manner. As will be quite apparent to those skilled in the art as the piston 11v moves downwardly on its intake stroke, the exhaust valve will be closed and the intake valve opened. As the piston moves upwardly on its compression stroke, both valves will be closed. The ring/then `takes place and the piston proceeds downwardly on its power stroke with both valves closed and as it moves upwardly on its exhaustI stroke the exhaust valve will open and the intake` valve remain closed. The valvesonly move when the pin 22 engages the top or bottom of the loops .21. lt is to be understood that the connecting rods extend between these loops. rhis lost motion connection is very important in that it allows the valves 'to remain open a predetermined length of time and allows them to'remain closed to be openedv only at the proper interval of time. This lost motion also enables the valve to be constructed as is shown in the drawings so Vthat they do not move above'the cylinder' head as would be necessary otherwise.- The valves are heldfrictionally in the slideways by a cover. plate 26 which also extends downwardly to be engaged with the Acrank case so as to prevent the irt getting through the openings 19. f

It is thought that the construction, operation, and advantages of this invention will now be clearly understood by those skilled in this art without a more detailed description thereof. The present embodiment of the invention has been diszlosed in detail by way of exam le since in actual practice, it attains the eatures ofY advantage enumerated as desirable in the1 statementof the invention and the above description. It will be quite apparent however,

110 struction, and in t 'e combination vand arrangement of parts may be resorted to without departing fromL the spirit or scope of the. invention as hereinafter claimedor sacrificing any of its advantages.

Having thus described my invention what I claim as new is:

1. In an internal combustionengine, the

vcombination of a cylinder having a vertical slide-way on .the exterior thereof, a valve including a bar-like body having extending [from one end thereof a pair of loops, a crank-shaft 4for the operation of said valve,

a connecting rod engaged with said crank f lshai't and having a laterally extending pin at one end,y said one end extending between the loops with the pin ridable in the loops so as to form a lost-motion connection between the crank shaft and the valve to transfer the rotary motion of the crank shaft into vertical rectilinear motion of the valve for'the purpose of closing and opening inv maar-ie ond crank shaft will rotate at' one-fourth` crank shaft speed, said cylinder provided with slidelways and ports communicating therewith, valves slidable in the slide-ways, each `valve including a bar-like body and having its lower ends provided with a pair of spaced parallel elongated loops, connecting rods associated with the second crank shaft and having transversely extending vpins ridable in the loops. v

In testimony whereof I aix `my. signature. 'A
